Passive and active direct liquid cooling for modules and chassis immersion implementations are becoming more commonly used to cool high-wattage devices — such as graphics processing units (GPUs) and switch application-specific integrated circuits (ASICs). This seems to be driving an expanding fluid connector and cable market with higher-volume units as applications now include hyperscaler and […]
Basics
D-sub connectors: Everyone speaks of them incorrectly
You probably don’t know it, but you’ve been referring to most D-sub connectors incorrectly for your entire career.
What is the common impedance of a twisted pair?
Understanding impedance in twisted-pair cables help you avoid signal problems.
The connector is often the EMI problem
It only takes 3µA of current to fail an EMC test, and a connector can produce that much.
Wire and fiber optic geometries offer high-speed cable transmission options
The latest high-speed transmission cables are benefitting from the use of optic-fiber and copper wire options, which are offering unique form factors and customizable solutions. Typically, data-transmission copper wire and optical-fiber conductors are round or cylindrical. The addition of silver plating on the copper conductor facilitates the high-frequency electrical transmission path. Fiber conductors are foundry […]
The evolution of woven fiber optic circuit boards and connectors
During the ’60s and ’70s, the early mainframe computers and Telcom switches used complex dense wire-wrap technology. High-circuit-count copper backplanes and midplanes often relied on wire-wrap point-to-point, or pin-to-pin layouts. This involved lots of hook-up wire and singular micro-coax for the clock circuits. The wire-wrap pin backplane connectors at that time typically had round-wired edge […]
Four types of connectors for robots and drones
Many power and signal connectors are used in robot and drone sub-systems, such as sensors, motion, high-speed wired and wireless communications, and more. As industry 4.0 continues to unfold, more robots and more types of robots are being found in factories, warehouses, and other facilities to increase quality and efficiencies and reduce costs. Robots and […]
Six key considerations when selecting and integrating GHz connectors into 5G applications
Connectors are essential components in radio frequency (RF) systems, especially in high-frequency applications like Gigahertz (GHz) 5G devices. Designers have a broad range of connectors to choose from, but there are a few key parameters to consider when narrowing down the choices. Six keys to selecting and integrating GHz connectors include physical size, frequency range […]
What’s the status of EV charging connector standards?
Connectors for electric vehicle (EV) charging are both standardized and changing. On one level, EV charging connectors are standardized based on today’s technology limitations. There are standards in major regional markets, including North America, Japan, the European Union, and China. But current charging technologies are power limited. This FAQ begins with a review of EV […]
A complete guide to modular connectors
First developed in the 1960s and becoming more publicly available in the early 1970s, modular connectors were born out of necessity to provide a more simple, “modular” interconnection system for phone systems, data networks, and low-speed serial connections. During that same timeframe, the FCC developed a registration system for modular connectors, known as Registered Jacks […]
